ahmed gatri , Here you can find service manual. Troubleshoot should start from power supply Start from basic level, Visual inspection Check 120uF 450V (primary)capacitor Swollen ? if yes replace it Check secondary caps 100ouF 35V caps swollen ? if yes replace them Check the output voltages mentioned on the circuit board Check the optocoupler resistance : primary around 8Mohms secondary 2-3Kohms : if any deviation replace it let us know if above steps not works to fix your TV then we can check the TV motherboard
